ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 496,666, dated May 2,1893.

Application filed July 19, 1892.

To aZZ whom it may concern.-

Be it known that I, STACY B. OPD YKE, J r., a citizen of the UnitedStates, residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Elevators,of which the following is a full, clear, and exact description,referencebeing had to the accompanying drawings, which form a part of thisspecification.

In the operation of elevators as at present carried on the persondesiring to go up or down from any floor is obliged if there be morethan one elevator car to find which elevator is the one approaching thelanding in the direction the passenger desired to proceed, and then toring a hell or wait until the elevator car approaches and call upon theoperator to stop.

My invention has for its object to enable a passenger at any landing toindicate to the operator of the elevator car ascending or descending,dependent upon the direction the passenger desires to proceed, beforethe ele vator car reaches the floor where the passenger 15.

I will now describe an embodiment of my invention.

In the drawings-Figure l is a sectional elevation showing the elevatorshafts, and their appurtenances. Fig.2 is an enlarged sectional view onthe line 50- 1; Fig.1 showing the cam about to engage with one of thepins on the rock shaft. Fig. 3 is an enlarged front elevation of the camway and signaling apparatus. Fig. 4 is a side elevation of the cam way.Fig. 5 is a detached perspective view of the rock shafts. Fig. 6 is adetached perspective View of a portion of the other rock shafts. Fig. 7is a modified form of connection between the pin and the signal. Fig. 8is a section on line ,zz, Fig. 7.

A A are two elevator shafts and B B are the elevator cars or cages whichmove in said shafts respectively.

0 O C are three floorsabove the bottom of the elevator shaft. At a pointslightly above each floor are the shafts D D D and at a point slightlybelow each of these floors are the shafts E E E respectively. Upon theshaft D at points opposite each of the Serial No. 440,525. (No model.)

shafts A and A respectively are pins (Z d and in the same manner uponthe shaft D are the pins (1 d and in the same manner upon the shaft Dare the pins (1 (Z and upon the shafts E are the pins e e, and upon theshaft E are the pins 6 e and upon the shaft E are the pins 6 e Shafts DD, E E are supported in bearings and adapted to be rocked. These shaftsD and E, D L, D E are shown in detail in Figs. 5 and 6 where they aremarked D and E. Connected to the end of the shaft E is the arm F whichconnects to the cord F which is of length sufficient to be operated fromthe floor 0, and in the same manner the shafts E and E are connected tocords corresponding as described with reference to E. Attached to theshaft D (and in the same manner D D) is the treadle lever G, which isadjacent to the floors 0 O C respectively, so that by bringing the footupon the lever the shaft D is caused to be rocked, and by pulling thecord F,the shaft E is caused to be rocked. Upon each of the elevatorcars or cages B and B are cams H H, said cams H being in line with thepins (Z (1 (Z (Z d (Z and the cams H are in line of movement with thepins e e c e e 6 Both the cams H and H are secured to the elevator carsor cages B B by means of the slotted links I I to which slotted linksthey are either secured or formed together with.

t' 1"2 d are screws which secure the slotted link to the frame of theelevator cars or cages B B respectively.

The cam way is shown in detail in Fig. 4 which shows the same at one endhigher than at the other end. At one end of said cams H H are the arms/b h, which arms are connected by a cord h with the bell h. In place ofusing the cord as aconnection with the bell, the arms h h may be made apart of an electric circuit 7%, in which the bell clapper is alsoinserted, as clearly shown in dotted lines Fig. 3. Each one of the rockshaftsD DD E E E is provided with a counterweight and with pins equal innumber to the elevator cars, two being shown in the drawings, as shownclearly in Figs. 1, 2 and 5.

As may be seen from an inspection of Fig. 1, the cams H and H are of thesame construction with the exception that their position is reversed;that is, the upper portion of the cam H corresponds to the lower portionof the cam H, or rather, is in the position of the lower portion of thecam H, the cams be- "5 ing merely reversed. Thus, the cam H is adaptedto be operated by the pins d, d, 61 ,01

(1 61 as illustrated in Fig. 3,and the cam H,

as shown in Fig. 1 is merely the cam H reversed. Connected to the cams Hand H at their upper and lower ends are the springs S S. These shafts D,D, D are for indicating the ascending elevator car, while the shafts E,E, E are for indicating the descending elevator. Taking the left handelevator car I which is descending, the passenger upon the floor Cdesires to have the elevator oar stop. He pulls the cord F, which rocksthe shaft E, bringing the pin 6 in alignment with the cam H, and whenthe elevator car reaches that point the pin enters the cam ways movingthe cam over as shown in dotted lines, and thereby making either anelectric circuit or pulling the cord h and ringing the bell, therebyindicating to the operator that on the next floor below there is apassenger to be taken on.

The construction of the cam way, as hereinbefore described, causes thepin when it reaches the ascending portion of said cam way to turn uponits pivotpoint, so that when 0 said pin has reached the highest point ofthe cam way, the pin is disengaged from alignment with the cam way.

Taking as the ascending elevator, for instance, the elevator car on theright hand side,

if a passenger on the fioor O desires to enter said elevator and ascend,he places his foot upon the treadle G, causing the pin to rock in shaftd to come in alignment of the cam way H, when the said operation asbefore described taking place with the cam H takes place with the cam Hand the operator is apprised before he reaches the floor 0 of the factthat a passenger is there desiring to enter the elevator car. Thepositions of the as- 5 cending rocking shafts D D D is at a point soslightly above the floor that the operator has ample time for theindication of the person upon that floor desiring to ascend to stop theelevator car while the ascending rock shaft E E is in such positionabovethe floor to which it relates that the operator has ample timeafter receiving the indication to stop the elevator and allow the personto enter. WVhen the cam ways are moved out by the pin as shown in thedotted lines, they are moved against the spring S, which when the pin isreleased from the way brings back the cam to its normal position. If,for any reason the counter-weights were not used for the pins or theyfailed to return to their normal position, the

ascending pin could then operate upon its cor-.

responding cam way when the elevator was asscending,but would notoperate upon it when descending for the up per portion of the ascendingcam is out of alignment with the pin which would cause said pin merelyto strike the side of the cam which would move it in the directionopposite and against the spring without indicating by the bell. The sameis true of the descending cam and its corresponding pin.

If desired, instead of making the electrical connection between the camand its signal, as shown in the drawings, heretofore described, I canmake my cam in two parts, h 71 separated by a strip of insulation, h asshown in Fig. 7, and provide an electrical circuit, h, which isconnected with the signal, h and one wire going to the binding post h onthe strip h, the other going to the binding post, It on the strip h, thepin (1- being of size sufficient to cover and extend beyond the insulation, W, and touch the two parts, 7t, 7t, of the cam,the pin being ofmaterial adapted to conduct electricity. When the pin is operated asbefore described and brought into line with the cam it will pass alongthe cam upon the insulated surface touching the two portions, h h of thecam H and thereby complete the circuit from the source of current supplyto the indicator so that when the pin passes over the cam the electricalcircuit is completed and the signal given.

I do not intend to limit myself to the specific form of constructionherein shown, as it is evident that the details may be modified in manyways without departing from my invention; nor do Iintend to limit myselfto the means shown for operating the pins except wherein the same arespecifically set out.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is-
